INSTALLATION INSTRUCTIONS

SAFETY

For CSS-O,C ensure that all power sources are disconnected and locked out before installation as severe injury or death may result from electrical shock due to contact with high voltage wires.

This product is not intended to be used for life or safety applications.

This product is not intended for use in any hazardous or classified locations.

INSTALLATION

Make sure that all installations are in compliance with all national and local electrical codes. Only qualified individuals that are familiar with codes, standards and proper safety procedures for high voltage installations should attempt installation. The current switches will not require external power, since the power for the current switch is induced from the conductor being monitored.

The current switch may be mounted in any position using the (2) #8 x 3/4 in. (19 mm) Tek screws and the mounting holes in the base or snapped directly on to the 1-3/8 in. (35 mm) DIN rail (See Figures 1 and 2). Leave a minimum distance of 1 in. (25 mm) between the current switch and any other magnetic devices, such as contactors and transformers.

For applications in which the normal operating current is below the 0.8/2.0 Amps trip point (See Fig. 3), the conductor being monitored may be looped through the sensor 6/12 times giving you a total operating current of 6/12 times the original current.

Example:

A small fan operating at 0.2 Amps can be wrapped through the sensor 6 times to give you a total operating current of 1.2 Amps flowing through the CSS-O-A300-001. Another option is to use CSS-OA200-001. A small fan operating at 0.2 Amps can be wrapped through the sensor 16 times to give you a total operating current of 3.2 Amps flowing through the CSP-O-A300-001. Another option is to use the CSP-O-A200-001.

Never rely on the LEDs to determine whether power is present at the current switch. The red LED will indicate whether the current is above the adjustable trip point. The green LED will indicate whether the current is below the adjustable trip point.

IMPORTANT

The current switch should be used on insulated conductors only!

WARNING

CAUTION

For applications in which the normal operating current is

greater than 250 Amps or for conductor diameters larger that 3/4 in. (19 mm) in diameter, and external 5 Amps Current Transformer (C.T.) must be used as shown in Fig. 4.

Latch Operation

Pressing down on the two (2) side tabs and swinging the cover open opens the split core current switch as shown in Fig. 5. Lifting up the latch with a flat-tip screwdriver as shown in Fig. 6 can also open the unit. Press down firmly on the cover to close the current switch. An audible “click” will be heard as the tab slides over the tongue on the base.

Mating surfaces of the magnetic core are exposed when the sensor is open. Silicone grease, present on the cores to prevent rust, can capture grit and dirt if care is not exercised. Operation can be impaired if anything prevents good contact between pole pieces. Visually check the mating parts of the core before closing the current sensor.
